Description

  The present invention relates to a paper processing apparatus for performing processing such as forming holes in paper.

  2. Description of the Related Art Conventionally, a sheet processing apparatus such as a punch for forming a binding hole in a sheet (for example, see Patent Document 1) or a binding machine (for example, see Patent Document 2) that can bind a plurality of sheets is known. It has been.

  By the way, of the above-mentioned paper processing apparatuses, focusing on the punch as an example, the conventional one has a gauge supported so as to be able to project and retract with respect to the punch body having a paper receiving surface in order to position the paper. There is. Such a gauge is provided with a stopper that abuts the edge of the paper on the leading end side, and the position of the standing stopper is adjusted by moving the entire gauge into and out of the punch body. It is used for positioning of the paper. Especially the thing of the said patent document 1 is comprised so that a stopper can operate | move with respect to a gauge so that a stopper can stand up from a gauge only at the time of use.

  However, in such a case, the stopper is accommodated in a state where it does not stand up with respect to the punch body so that the gauge projects and sinks with respect to the punch body. That is, the sheet cannot be positioned in the posture in which the stopper is accommodated in the punch body. Therefore, the user must always adjust the position of the stopper to a predetermined position every time it is used. In other words, in the past, there is no exception when using it, and in addition to the operation for setting the gauge to the expected position, the position of the stopper is adjusted to a position where it can contact the edge of the paper. Multiple actions are required. As a result, the use of the gauge itself gives the user an impression that it is complicated. Further, even when the gauge is not used, if the stopper is in an upright state, the stopper may interfere with the paper and impair workability. In other words, in the conventional gauge, in addition to the operation of operating the gauge, a special operation for making the gauge usable is required. Such an extraordinary operation may give the user the impression that handling of the gauge is complicated.

  Of course, the same problem occurs when such a gauge is applied not only to a punch but also to a binding machine or a stapler. In other words, conventional gauges can cause the above-mentioned problems without exception when applied to a paper processing apparatus.

  The present invention pays attention to such a problem, and an object of the present invention is to provide a sheet processing apparatus that is easy to perform an operation for surely setting a gauge at an intended position.

  In order to achieve such an object, the present invention takes the following measures.

  That is, a paper processing apparatus according to the present invention includes an apparatus main body having a paper placement surface, a processing mechanism that is provided in the apparatus main body and processes the paper placed on the paper placement surface, and the apparatus main body. A sheet processing apparatus provided with a gauge that is slidable between a storage position and a use position and that positions a sheet placed on the sheet placement surface at the use position; A gauge raising / lowering mechanism for raising and lowering the gauge by using a sliding operation of the gauge is provided.

  Here, “raising and lowering the gauge” is not limited to the one in which the entire gauge performs the raising and lowering operation. That is, as long as the slide operation is used, the entire gauge may be lifted or lowered by a specific part of the gauge. Here, as an example of the raising / lowering operation of only a specific part of the gauge, there is an aspect in which the stopper provided integrally or separately from the gauge is moved up and down while the upper end position of the stopper is changed. In addition, for example, the upper end of the stopper, which is a part of the gauge itself, moves up and down due to a sliding operation that involves a reciprocating operation in which the stopper, which is a part of the gauge, stands up from the folded state and then falls from the standing state. It is a concept that includes operation. Needless to say, the above-described part of the rotation and standing / falling of the gauge may be performed along with the raising and lowering of the entire gauge. In addition, the gauge raising / lowering mechanism according to the present invention is a concept including an aspect in which the gauge does not have a stopper but is raised and lowered to a position where it can easily act on the paper in the use position.

  If it is such, if a gauge is made to slide by a gauge raising / lowering mechanism, it can be made into a required use position for a user by raising / lowering naturally. As a result, the user need only perform a sliding operation when using the gauge. That is, according to the present invention, it is possible to provide a paper processing apparatus that is easy to perform an operation for reliably setting at least a gauge at an intended position.

  As a specific configuration of the gauge lifting mechanism that facilitates processing on the paper at the use position, the gauge is slidably supported on the apparatus body, and the gauge body is provided at the outer end of the gauge body. A stopper for locking the edge of the paper, and the gauge elevating mechanism has the upper end of the stopper located below or substantially flush with the paper placement surface in the storage position and the use position. In the configuration, the gauge is moved up and down so that the upper end of the stopper is positioned above the sheet placement surface. In such a case, in the storage position, the upper end of the stopper is positioned flush with the paper placement surface or below the paper placement surface, and the gauge is placed in a suitable position and posture that does not interfere with the paper. Can be stored.

  As an effective configuration for stabilizing the sliding operation of the gauge, the apparatus main body includes a base having the paper placement surface and a receiving base attached to the lower surface side of the base, A configuration in which a gauge holding portion including a bottom surface that supports the gauge body from below and a guide side surface that guides the gauge body from the side surface is provided on the receiving bottom.

  In addition, in order to achieve both the accurate slide operation of the gauge and the lifting operation by the gauge lifting mechanism with a simple configuration, the gauge body has a shape in which the vertical thickness dimension gradually decreases from the inner end toward the outer end. It is desirable that only the lower surface of the inner end portion is always in sliding contact with the bottom surface of the gauge holding portion. According to such a configuration, the operation of the gauge raising / lowering mechanism is realized by raising and lowering only the outer end of the gauge.

  If the gauge lifting / lowering mechanism is configured to lift and lower the gauge main body by a slide cam mechanism provided between the apparatus main body and the gauge main body, accurate paper positioning and reliable by the gauge can be achieved. Both raising and lowering can be achieved.

  As a specific configuration for realizing a stable operation of the gauge, the slide cam mechanism is located on the side of the gauge main body, and on the inner end side of the lower rail. An upper rail projecting on the side surface of the gauge body, and a lower guide surface projecting on the inner surface of the gauge holding portion and engaging the inner end of the lower rail to guide the gauge body in the downward direction. In addition, a configuration including a guide protrusion having an upper guide surface that engages with the outer end of the upper rail and guides the gauge body in the upward direction can be given.

  In addition, in order to realize further simplification of the configuration of the gauge, it is preferable that the gauge has a gauge body and a stopper integrally formed.

  The present invention can be preferably applied to the processing mechanism for forming a hole in a sheet.

  According to the present invention, it is possible to provide a paper processing apparatus that is easy to perform an operation for reliably setting at least a gauge at an intended position.

The specific relationship between the upper guide surface 54 and the lower guide surface 55 and the gauge body 3 will be described in detail later.

  The gauge G is used to position the paper with respect to the punch body 1 in order to determine the position of the hole formed in the paper. The gauge G slides between a position where the sheet can be positioned, that is, a guide position (g) protruding outward from the punch body 1 to a storage position (s) arranged along the punch body 1. And a stopper 4 that is provided so as to be movable with respect to the gauge body 3 and guides the end of the sheet at the guide position (g).

The position of the concave portion 56 is set so that the sliding contact convex portion 36 of the gauge body 3 can be engaged with the concave portion 56 at a position where the stopper 4 can be positioned. As described above, since the sliding contact projection 36 is always in contact with the bottom surface 51 while accumulating elastic repulsion, the sliding contact projection 36 elastically attaches the sliding contact surface 57 when the gauge body 3 is slid. Or is elastically engaged with the recess 56. Thereby, the moderation mechanism which can implement | achieve exact positioning of the gauge G easily is implement | achieved.

  Accordingly, in the present embodiment, as shown in FIGS. 8 to 13, the upper end 4a of the stopper 4 is positioned below the sheet placement surface M at the storage position (s) and the upper end 4a of the stopper 4 at the guide position (g).

  FIG. 8 shows a state where the gauge G is in the storage position (s). In this state, the guide protrusion 53 is in contact with both the upper rail 32 and the lower rail 33 of the gauge body 3. In particular, in the gauge body 3, the lower rail 33 is sandwiched between the clamping plane 55b formed at the lower end of the lower guide surface 55 and the bottom surface 51, and is positioned at the storage position (s). In addition, the upper rail 32 is in a state of slightly touching the curved surface 54 a provided on the upper guide surface 54. When the operation of pulling out the gauge G from the gauge holding portion 5 is started from the state shown in FIG. 8, the lower rail 33 and the guide protrusion 53 are separated from each other as shown in FIG.

  Further, in order to achieve both the accurate slide operation of the gauge G and the raising / lowering operation by the gauge raising / lowering mechanism X with a simple configuration, in this embodiment, the gauge body 3 is gradually increased in thickness from the inner end toward the outer end. Only the lower surface of the inner end portion is always in sliding contact with the bottom surface 51 of the gauge holding portion 5 by the sliding contact convex portion 36 while providing the tapered surface 34 whose size is reduced. Thereby, even if it is the simple structure of raising / lowering only the outer end of the gauge G, the reliable operation | movement of the gauge raising / lowering mechanism X is implement | achieved.

  In this embodiment, the gauge raising / lowering mechanism X raises / lowers the gauge body 3 by a slide cam mechanism provided between the punch body 1 and the gauge body 3. Both positioning and reliable lifting are achieved.

  In the present embodiment, as an effective configuration for realizing a stable operation of the gauge G, the slide cam mechanism includes a lower rail 33 projecting from the side surface of the gauge body 3 and an inner side of the lower rail 33. The upper rail 32 projecting from the side surface of the gauge body 3 positioned at the end side and the inner rail of the gauge holding portion 5 projecting from the inner surface of the lower rail 33 are engaged with the lower end of the gauge body 3 and lowered. A lower guide surface 55 that guides in the direction and a guide protrusion 53 having an upper guide surface 54 that engages with the outer end of the upper rail 32 and guides the gauge body 3 in the upward direction are provided.

  In addition, in order to realize further simplification of the configuration of the gauge G, in the present embodiment, the gauge body 3 and the stopper body 4 are integrally formed.
